CLOUD & STACK SECURITY
Engineering teams at SignalWire are continually working to create a best-in-class product
offering. The following guidelines help us to organize and achieve this goal at every stage of
Internal Security Designs
SignalWire engineers maintain a constant vigilance to ensure the security of our products
with activities including:
Static Code Analysis
SignalWire developers use automated static code analysis tools to identify potential
vulnerabilities and security issues within the codebase. These tools can detect issues
such as SQL injection, cross-site scripting, and other common web application
SignalWire uses a dependency management system to ensure that all third-party
libraries and packages used in the codebase are up-to-date and free of known
vulnerabilities. This includes regular updates and security patches to ensure that any
known vulnerabilities are addressed as soon as they are discovered.
SignalWire uses threat intelligence feeds to stay informed about the latest threats and
vulnerabilities. This includes monitoring industry-wide security advisories, feeds from
security researchers, and subscribing to threat intelligence feeds from leading security
In addition to monitoring these external sources, SignalWire also employs Intrusion
Detection and Prevention Systems (IDS/IPS) software to proactively detect and prevent
potential threats on our network. This software continuously monitors our network traffic,
looking for patterns and anomalies that may indicate a security breach. The software is
configured with a set of rules and signatures that are continuously updated to detect the
latest known threats. Our team also monitors the software logs and alerts on a daily
basis to detect and respond to any potential threats.
SignalWire engineers implement advanced encryption methods such as HTTPS and
secure websockets to ensure that all data transmitted between the client and our servers
is encrypted and secure. We also use advanced encryption methods such as AES-256
and RSA-4096 to protect sensitive data stored on our servers. SignalWire supports TLS
1.2, 1.3 to encrypt network traffic between the customer application and SignalWire.
Encryption at Rest
SignalWire uses encryption at rest to protect data stored on disk. This includes using
industry standard encryption algorithms such as AES to encrypt customer data and
using key management systems to securely store and rotate encryption keys.
Continuous Security Improvements
Our engineers are constantly researching and implementing the latest security
technologies and best practices to improve the security of our products. We regularly
conduct security assessments and penetration testing to identify and address any
potential vulnerabilities in our systems.
Account Security Measures
SignalWire implements a variety of advanced account security measures such as
multi-factor authentication, password hashing, and user session management to protect
our clients' sensitive information.
Vendor Security Audits and Certifications
The cloud hyperscalers that SignalWire uses are regularly audited by independent
third-party organizations to ensure that they comply with the latest security standards and
regulations. This includes certifications such as SOC 2, ISO 27001, and PCI DSS. By
leveraging these certifications, SignalWire is able to provide its customers with an added
layer of security and assurance that their data is being protected to the highest standards.
Security Awareness Program
We have implemented a comprehensive security awareness program to ensure that all
personnel are aware of the importance of security and understand their role in maintaining
the security of our systems and data. This program includes regular communications and
education on security topics and best practices, as well as simulated phishing attacks to
test and reinforce employee awareness of potential security threats.
Access to infrastructure, networks, and data is tightly controlled to only those persons or
services that require direct access. Encrypted overlay networking helps to prevent any
possibility of data leakage during transmission along with mandatory SSL encryption of all
control plane and messaging bus protocols. Production services are only accessible
through a tightly curated, audited list of employees utilizing only certificate authentication
for login or deployment scenarios. This ensures that only authorized personnel can access
our infrastructure and customer data. All identity is centralized and managed by an IAM.
